Quizplus · Accepted Answer

Refraction is the bending of light when it passes from one medium into another. Snell's law is a formula that is used to describe what happens to light when it passes between two mediums in terms of the angle of incidence and angle of refraction. It also uses the index of refraction, which is a dimensionless ratio between the speed of light in a vacuum and the speed of light in a certain medium.
